To all 'whom it 'mo/y concern;

Be it known that l, JUs'rUs R. KiNNnY, a citizen of the United States oi' America, and a resident of Dorchester: in theI county 'of Suffolk and State of Massachusetts, have invented certain new and useful Improve- .ments in' Rotary Motors or Pumps, of which the -following is a specification.

This invention relates to rotary motors and pumps,A and has 'for its object the production of such a motor or pump, the casing of whiehis provided with a cylindrical chamy uber, in which is ceeentrically mounteda rotary piston, the periphery of which is provided with a band capable of peripheral adjustment on said piston, said piston being also provided with other means for-adjusting the position o'lfsaid band toward and lrom 'the axis of said piston to take up the wear and insure contact between the piston and the'cylindrieal walls of said cl'iainber.

l The invention consists also in certain Qvel 4features of construction and arrangements of parts which will be readily understood by reference to the description 'ol" the drawings Vand te the claims hereinafter given.

Of the drawings: Figure 1 represents a sideelevation of a device embodying the features oi this invention. Fi?. 2 represents a section of the same on line 2-2 on Fig. 1, the operating com being cut in section o n line lll-2" on Fig. 1. Fig 3 represents a vertical section online BH3 on Fig. 2. Fig. 4 re resents a sectional' detail 'on line 4 on` Fig. 5 represents a perspective View of the piston segment, and Fig. 6 represents perspective view of the cylindrical band for said pistou segment.

Similar characters designate like parts throughout the several figures of the drawfinds.

du the drawings, 10 represents a suitable l-)aseupoii which is mounted the casing 11 rovidcd with the cylindrical chamber 12. Extending transversely through the casing 11 is a shaft 123 to which is secured by the set screws 14 a segment of a cyliiiderd` the perii'ilieryof which is eccentric to the peripheral .wallsofthe chamber 12. Upon the "outer periphery of the segment 15 is mounted a continuous cylindrical band 16 the diameterofwhich'is such as to extend to and com *toot 1Vith the inner eriiiliei'al walls of the chamber 12 when mounted upon said segment. Against the inner tace ol said band 1G are a i'ilurality oi shoes 1T havingr pivot- 18, while other threaded members 19 are suitably mounted in the segment 15 and extend radially there. from.

interposed between the threaded members 18 and 19 is a turiibuckle 2t) by which the slices may be forced outward to lorce the band V1G outwardly to retain it in contact with the wall ol' the chamber 12. This band 16 is made suilicieiitly ilcxible to pci-mit this to bc accomplished. lt is obvious that this contact may be secured when the baud is to bring the band into contact with the cylindrical walls ol thc chamber 1.2 but :is the ing the rotation ol" the piston these adjusting devices may be again operated lo stretch the band slightly and to again l'orcc its outer peri ihery iiito contact with the cylindrical wall oll the chamber. yWhen thc band has been stretched in this manner to ilstlimit it is obvious that by a slight distortion of the band the point 21 may be iliade to contact with the cylindrical wall oll the chamber while the slices 17 on either side thereof are moved slightly inwardly toward the axis ol the shaft 13 to permit of this distortion. When the point 21 of the band is worn Vto any extent it is obvious that by operating the adjustingl meii'ibers and loosening the band 16 this band maybe moved about the eriphery of theI segment thereby bringingr a Eesli coucentric portio'n ol' the band into position to contact with the cylindrical wall ot the ohaii1- oer 12. With the outer periphery of the band 16 cooperates n shoe 22 pivotally connected at 23 to a blade 24 slidably mounted in a chamber in the iiiembor 25 secured to the pivotal shaf t 26 about the axis of which it is moved` The outer end of the shaft 26 has 'secured therein a lever 27 the free end of which is provided with a truck or roller which cooperates with the path 29 in theoam 30 secured to the shaft 13 by means of the set screw 31. The enter of the cani'fpath 29 conforms to the periphery of the band 16 so that any movement of the lever 27 caused by i. the cani path 2Q will cause a similar move-2 new by simply adjusting` the tiiriibuclzlcs 20j ally connected thereto threaded members mnd WMS by .its Contact wi 'ih thc wall durthe nivoted member 25. it is obvious thereiore that ae'the eem path enti tite henri i6 conform to each other the shoe 22 ffii 1oe meehenieeiiv .heid in eonteet with tire riphery of the bend lo et eil times.

The pivotoi emineetion between the shoe 22 and the redini hhuie 2?.- permits seid shoe to rook about the pivot-ai connection to con.- orm to the verving positions of the eoeenti piston ponti t6. Should there he any in-l equalities in the henri no it roto-tee about its exis, as, for instance, when it has oet-omo worn or when it hits heen distorted slightiy from its cylindrical elmpe hy the adjustment of the devices interposed between the hond and the segment. 15, the hlmle 24 is adopted to move rodiaily egeinst the tension oi" the spring-g 32 which normally retains the shoe 22 in Contact with the periphery o" the hand i6'.

The shoe 22 moves through un openingl 33 also serving es en outlet when the tieviee is used as a motor and :in inlet when the device is used as a pump. This opening 33 eemmunieates through the passage 34 with a, suitable pipe secured to the flanges o? the easing 11 in any Welt-known manner. The easing? 1l is oleo provided with another pas sage 36 communicating with the ehemher i12 at a point in close proxin'iity to the shoe The passage et the liquid or om] other element through said :Lesage is regulated oy the valve 37 which las secured to its outer end en erin 38 the free end of which is piro ideal with e truck 3Q eooperatingvfith e, com throw i0 which tete upon said erm to open end eiose the `vaive 137 es required.

A pipe 42 is secured to the Hongos of the easing li in any well-known manner. it is obvious from en inspection of the drawings that the cani throw 4G moves the truck 39 outwardly from the axis of the shaft 13 While the spring; 4i operates upon the arm 3S to retain said truck in Contact with its cern at 'all times. 45'

In the operfttion of the device when in use as a motor the steam or other motive ioree is admitted through the pipe 42 sind es the point 2l ot the piston hond 1.6 reaches the position showin in Fig, 3 the (zum 40 oomn'ienees to operate upon the truck 3Q to open the valve 3T and permi the motive 'force to pass through the peseago into the interior of the chamber i2. inasnnieii the eiwit-- ment' 22 prevente the motive force from passing' in the direction of the outiet 33 from the eliarnber l2 it is obvious that this motive torce Wil directed in the opposite fiireetion and eeuse the piston to be moved in the direction ot the arrow on Fig. AS the piston mov-es about its axis the valve 37 closes and the motive force 'beek of the piston is permitted to expend this expansion essistinrbin the inoveinei'it of the piston about its exis. hen 'the fleviee need pump tile piston is driven in the oppoe rotation to the errmv on Fil-2;'.
